Grand Wash Springsnail
Pyrgulopsis bacchus
The Grand Wash springsnail (Pyrgulopsis bacchus) is a species of freshwater snail in the family Hydrobiidae, the mud snails. It is endemic to Mohave County, Arizona, in the United States.
The snail is known only from Grand Wash, a watershed near Lake Mead. Shells that may belong to this species have also been collected in southern Nevada. The snail occurs in a few springs in its range, where it feeds on algae and detritus. Though very limited in distribution, it can be abundant in its native springs, with up to 50 individuals congregating on a single leaf in the water.
